Design and analysis of heat transfer on a customized eco-print batik steamer with automatic temperature and time control using Computer Fluid Dynamic (CFD)

Abstract

The process of making eco-print batik carried out by eco-print batik industry players still uses conventional methods with steaming pans. The conventional method used has a quite crucial impact on the equipment used, the bottom of the pan is susceptible to damage because it is used continuously for quite a long time. To overcome this problem, a steamer design will be created specifically for eco-print batik using Solid Work software. Following the completion of the design, this research investigates how the heat transfer process occurs, the circumstances of the heat flux created, and the temperature during the heating process using computer fluid dynamics (CFD) with simulation methods as an approach to real conditions. Observations were made in 300s, 600s, 900s, 1200s. The steamer material employed in this simulation is stainless steel 304, and the simulation results show that the steamer's heating temperature is. Based on the simulation results of high pressure in closed system conditions and the influence of materials with good thermal conductivity on the steamer, which have an impact on increasing temperature and heat flux during the process, through these considerations, the steamer is designed to be equipped with temperature control and a safety valve which functions to release pressure. steam when excessive. In this way, the steamer will be more effective and efficient in terms of time, heating, and the quality of the batik results that will be produced later when compared to the pan used previously.
